New URL spoofing bug in Microsoft Internet Explorer

There is a security bug in Internet Explorer 6.0.2800.1106 (fully
patched), which allowes to show any faked target-address in the status
bar of the window.

The example below will display a faked URL ("http://www.microsoft.com/";)
in the status bar of the window, if you move your mouse over the link.
Click on the link and IE will go to "http://www.google.com/"; and NOT to
"http://www.microsoft.com/"; .

<a href="http://www.microsoft.com/";><table><tr><td><a
href="http://www.google.com/";>Click here</td></tr></table></a>

Description: Microsoft Internet Explorer can't handle links surrounded
by a table and an other link correct.

The bug can be exploited using HTML mail message too.

Affected software: Microsoft Internet Explorer, Microsoft Outlook
Express, ...

Workaround: Don't click on non-trusted links. Or right-click on links to
see the real target. Or use Copy-and-Paste.
